   Converts a type to its string representation and back.

   Converts a type to its string representation and back. For creation of the type from a string the create_... methods are used.

   Automatically supported types are: $ - collection types (immutable preferred): List, Seq, Vector, Set $ - all classes deriving from Product, including case classes and tuples

   If a new type NewType shall be supported, the TypeConversions has to be extended with the create_NewType(str: String) method. The conversion to a string is simply done by calling the object's toString method - Strings themselves are surrounded by quotes.

   If a new type (or an existing one) shall change the conversion to a string, the appendString(Any, StringBuilder)-method has to be overridden.

   Example: extend TypeConversions for java.io.File, where its String representation is mapped to the file's absolute path

   val config = ConfigMacros.wrap(classOf[Config], props.getProperty, props.setProperty, new TypeConversions {
     def create_File(filename: String) = new File(filename)
     override def appendString(any: Any, buf: StringBuilder) {
       any match {
         case file: File => buf.append(file.getAbsolutePath)
         case any        => super.appendString(any, buf)
       }
     }
   })
